B2BMessagingSync
About the API
The B2BMessagingSync API is used to send and receive B2B messages between the participants in a synchronous fashion.
Messages are delivered between participants in a blocking thread for example, the Initiator sends the request to the Recipient and the Recipient is expected to send the response (MACK Reject / TACK Reject / Response) in the same blocking thread.
Getting access
AEMO provisions access to participants or intending participants in accordance with the accreditation process outlined in the B2B e-Hub Accreditation Process.
During formal onboarding, you are first provided access to Pre-Production and must complete your development/testing there prior to getting access to Production.
FAQ
Q: Can I send my message in JSON?
No. The B2B Messaging APIs only support xml payloads, specifically the aseXML standard. For details on how to use the aseXML format see: aseXML standards
